Broad Question

How does candle temperature affect candle height?

Specific Question

Will a candle at room temperature freezer temperature and above room temperature have more wax after two minutes of burning?




Variables

Independent Variable: Candles

Dependent Variable: Height of Wax (mm)


Variables That Need To Be Controlled:

  1. Same candle type
  2. Same match or lighter
  3. same amount of burning time

Hypothesis

I hypothesize that the candle that has been in the freezer will have more wax, next will be the candle at room temperature then above room temperature.

Experimental Design

I will be going to conduct my experiment at my house in my kitchen. I will be the only one to do this experiment my roles will to go get the candles and place them in there spots for the five minutes then I will be taking them out and lighting them instantly after about two minutes of burning I will measure the wax that is left on the candle.
I will be going about five trials to get enough data to make my conclusion so that I can make a final statement on my experiment. I will be using a spreed sheet to place all my data in so I will not lose them on a computer and I will be Abel to send it to my google documents at school .I will be documenting my data on a computer so I can send it to schools document or I can print is out to put on a big poster board if needed and it also would be neat and I could edit essayer if needed.

Materials List


  • Candles
  • Lighter
  • Ruler
  • Clock
  • Refrigerator
  • Paper to right measurements
  • Pencil or p

Detailed Procedure


  1. Go to store to get birthday candles
  2. Put candles in a freezer
  3. Another in room above room temperature
  4. Last in regular room temperature
  5. Wait about five minutes for each candle to go to the temperature in there designated spots
  6. Take candles and light them instantly
  7. Record the wax that is left
  8. Repeat steps 2-7 two times

Background Research

  • a candle keeps its shape at room temperature. the bottom of the wick is the coolest part of candle. at the tip of the flame on a candle is the hottest part of that flame because it gets so hot that the gas rising turns into the fourth state of matter which is plasma.
  • gasses from a candle will push aside the oxygen and will then go onto plasma were it gets really hot and then releases the gas out into the air and the smell of the candle you are burning.
  • the heat that comes of a candle is like infared because it helps you see stuff when you can not see in the inviourment that you are in candle light has been a good source of heat and light easy to start esay to stop.
  • the light a candle gives off can be Sean a mile away from a sertant spot on a open flat field you can see it for two miles a candle flame is a very strong light force so it can be very reliable on a none windy day or raining it can show your way back.

Data Analysis

Results

The original purpose of the experiment was to see if there was a way to make candles burn longer than their original time of burning I had read that it was better to burn candles for a much longer time after it had been in the freezer. the results of the experiment was that if you left the candle in the freezer it would burn longer than the room temperature candle and above room temperature candle so that means if you want to have a candle longer put in the freezer for a long time.


Conclusion

My hypothesis was that the candle that had been in the freezer would have more wax left after I had completed the trials and the burning. My results do support my hypothesis because when the candles had been in there a period of time that candle had more wax . there is a relationship between the independent and dependent variables because when I was testing I used the same candle the same matches And same time for burning. the patterns that my tests show is that the height of each of the candles within each temperature category was very close to each other.I think the test went smoothly with minor trouble some of the troubles were lighting the candle when it just come out of the freezer it would warm up when I touched it. I would not improve my experiment because there isn't very much more I could have done. I don't think that there is a very much further stud for the future it's a very simple study.
